INCANDESCENT GAS-LIGHTING BURNER.

SPECIFICATION formingpart of Letters Patent No. 668,628, dated February 26, 1901.

Application iiled July 14, 1900.

To ctZZ whom, it muy concern.-

Be it known that I, GEORGES DELIN, man ufacturer, a citizen of Belgium, residing at '7 Boulevard Anspach,Brussels,in the Kingdom of Belgium, have invented certain useful Improvements in Incandescent Gas Lighting Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being'had to the accompanying drawings, forming part of this specification.

The object of this invention is to provide a novel incandescent gas-lighting burner provided with a mixing-chamber divided by a wire-gauze and a cylindrical conical-shaped aj utage having three compartments, the heights of which being adjustable, as may be desired, according to the richness and pressure of the gas by varying the distance between the upper and intermediate wiregauzes ,so asto quicken or retard the passage of the gaseous mixture. Said burner is also provided with a closing device surrounding the ejector and by which the gas-jet is prevented from being Iiickered by the ductuations of the ambient air and allowing at the same time the admission of the air for combustion.

The annexed drawings show two forms of construction of the improved burner.

Figure l is a vertical section of one form of the burner. Fig. 2 is a plan view of the same, partly taken on the line T T and partly on the line V V of Fig. 1. Fig. 3 is a vertical section of a second form of the burner. Fig. 4 is a plan view of the same,following the line X X of Fig. 3.

The mixing-chamber of the burner is closed at its upper end by a wire-gauze b where the combustion of the gas takes place and is divided into three compartments by the wiregauze a and the hollow conical-shaped ajutage m. The wire-gauze a and the aj utagem are intended for intimately mixing the combustible gas and air for combustion. In order, however, that the mixing may be perfect, it is necessary that the capacity of the three compartments of said mixing-chamber be capable of regulation according to the richness and the pressure of the gas. To this end the cylindrical-shaped portion of the Serial No. 23,601. (No model.)

ajutage m is split longitudinally by the sawnotches (kerfs) fn, so that the sections thus formed on the cylinder may act as a spring and impinge slightly against the inner wall of the tubes c d, and by this means the ring may be securely fixed in place at any convenient height and allow of varying said height as may be desired. The conicalY shaped portion of the ajutage is intended for retaining for a moment the air and gas flowing in, as indicated by the arrows in Figs. l and 3, in order to obtain an intimate mixing of the same, and the mixture may be preheated in passing against the walls of the ajutage.

Figs. 1 and 2 show a regulating device for adj usting the intermediate wire-gauze or perforated metallic sheet ain a relative position to the upper wire gauze or diaphragm b, which is stationary. As shown in Fig. l, the tube c of the diaphragm a contains a rack e, operated bya little pinionf, the spindle of which is revolved by means of the wheel h and extends through the notch g of the tube c, which allows the vertical displacement of this latter.

It is to be pointed out that the metallic diaphragms a, and b are preferably arranged in such a way that the wires of the diaphragm a intersect with those of the diaphragm b for the purpose of deliecting or twisting the ascending current of the mixture. The same result is obtained if the wire-ganzes are replaced by perforated metallic sheets and are placed in such relative position that the holes therein do not register. The application of the aj utage m and of the metallic diaphragms a, and b enables one to obtain an intimate and perfect mixing of the gas and air, which can only be performed by mechanical meanssuch as chocks, pressing, laminating, and so on-as has been proved by previous practical trials. The ajutage 'm and the metallic diaphragms are used for the purpose of producing said mechanical effects.

On its lower end the burner is furnished with a casing o, encircling the ejector It has a lid or cover o for preventing the gasjet from iickering under the influence of the undulations of the ambient air. Both the casing o and its lid o' are provided with apertures p 1o for the ingress of the air for com- IOO bustion. The section of the passage for the gas within the eject-or, and consequently the quantity of gas introduced to the burner, are regulated at will by means of a screws, which may have a square or triangular-shaped head, so that said screw should not be turned without a special key, and thus all disturbances would be prevented. In the burner shown in Figs. 3 and 4 lthe diaphragm a is stationary, while the diaphragm b, and consequently the space between them, are regulated by means of the intercalated rings Z l. These rings, which are of convenient breadth, are arranged between the ring 7a, the stirrup z', and the tube d of the upper wire-gauze b. The ring 7c serves also as bearer for the pipe c of the wire-gauze d. The intercalated rings aord the advantage that the regulation once made for any room or space to be lighted is made for all, so that one is relieved from adjusting it again. Moreover, the burner is not subject to any disturbance as to the position of the metallic wire-ganzes d and b by any cause whatever coming from cleaning or otherwise. It is also to be pointed out that the intercalated ringsl l' can be adjusted according to the composition and richness of the gas and provided with marks, which enables the burner to be regulated with the greatest ease.

In the burner shown in Figs. 3 and 4 the inclosing casing o is replaced by a simple gallery o2, extending beyond the lower edge of the ring 7c and having apertures p for the inlet of air. This gallery is adapted to fulfil the same purpose as the casing o o.

Having thus described my invention and ascertained in what manner it is to be performed, what I claim as new, and desire to protect by Letters Patent, is-

l. In an incandescent gas-lighting burner provided with a mixing-chamber, the combination With an upper apertured diaphragm, of a lower apertured diaphragm, a cylindrical conical-shaped ajutage, and means for adjusting the distance between the upper and the lower diaphragm according to the richness and the pressure of the gas, substantially as set forth.

2. In an incandescent gas-lighting burner provided with a mixing-chamber, the combination with an upper apertured diaphragm, of a lower apertured diaphragm, a cylindrical conical-shaped ajutage, and means for adjusting the distance between the upper and the lower diaphragm, the apertures in said diaphragms being arranged out of line with each other for the purpose of producing a thorough mixing of the gaseous elements, substantially as set forth.

3. In an incandescent gas-lighting burner provided with a mixing-chamber, the combination with two apertured diaphragms, of a rack and pinion for moving one of them toward and away from the other, for the purpose of accelerating or retarding the passage of the gaseous mixture, substantially as set forth.
